Collaborate on mockups

With Fluid UI, you’ll need to exchange drafts with your colleagues to collaborate on a project. Lucidchart lets you work together on projects simultaneously.

See updates from collaborators in real-time, and try the comment and video chat features for fast communication.

Extensive shape libraries

With a Pro account, you can make any type of diagram you need, including server rack diagrams, flow charts, org charts, floor plans, and more.

Customize the diagramming experience by turning shape libraries on and off as needed.
